Backyard Lazy River Cost
Having your own private lazy river winding through your backyard is a fun and luxurious way to enjoy relaxing summertime lounging.
But how much does it really cost to build your own backyard lazy river, and what all goes into such a project?
In this complete guide, we'll break down the full process and costs step-by-step so you know what to expect if you decide to take on this ambitious DIY project. By the end, you'll have a good idea of whether building a lazy river is feasible for your budget.
Estimating Materials Costs
The bulk of your costs will be for materials. Here's a breakdown of the key material expenses to budget for:
Tubing
- PVC tubing - around $3-5 per linear foot for 4-6" diameter PVC depending on quantity needed. Figure about $1,500-2,500 in tubing alone for a medium-sized backyard lazy river.
- Fittings like elbows and joints will add another $500-1,000 depending on complexity of design.
Pump & Filter System
This is one of your biggest purchases. Expect to spend $2,000-4,000 or more on a quality pump, filter, and all necessary plumbing hookups.
Decking
Decking material like composite or treated wood will cost $3-6 per square foot installed. Figure 400-800 square feet of deck needed depending on design, so budget $1,500-5,000.
Additional Materials & Supplies
You'll also need gravel, sand, concrete, liner material, flow valves, lighting, fencing, landscaping, etc. Budget another $3,000-5,000 for all ancillary materials.
In total, estimate around $10,000-18,000 just for materials before accounting for labor costs.
Figuring Labor Costs
How much you pay for labor depends greatly on whether you DIY or hire contractors:
DIY Labor
Doing most of the work yourself can save thousands, but expect to invest many weekends over 2-3 months if doing it alone.
Contractor Labor
- PVC Installation - $5-15 per linear foot installed depending on access and site challenges.
- Deck Installation - $40-80 per square foot professionally installed.
- Electrical/Plumbing - $100-150 per hour for rough work, more for finish work.
- Landscaping/Concrete - Quotes typically $100-300 per man hour depending on work.
With contractors, labor alone could easily approach $10,000-20,000+. Only DIY what you're comfortable with.
Additional Hidden Costs
Don't forget these other potential extra expenses:
- Permitting fees from your local jurisdiction (~$500-2,000 usually).
- Engineering inspection (optional but recommended for liability, $500-1,000 typically).
- Increased property taxes after adding the new permanent structure.
- Unforeseen challenges that drive additional material or labor costs.
- Maintenance/operating costs after ($500-1,000/year estimate).
